I wrote this letter at night just before Mr. Iino's leaving from Japan for your country. I am not so proficient in English
as to be able to write and hand him the English letter before his departure, so I wrote this letter in Japanese.
The letter written in Japanese style may be strange and somewhat amusing for you. I hope Mr. Iino will translate or explain
this letter, if you are unfamiliar in
First of all, I thank you for your kindness of sending me many reprints, and I pay my respects to your excellent studies.
My studies now concern on the factors affecting recombination, using two mutants (aspartic acid-biotin-nicotine acid less
and proline-cystine less) of Shigella flexinert[?], and find out the fact that the maltose locus play a important role on
the recombination of Shigella. I am now adjusting the results, and thinking to send them and strains to you.
I hope you will attend at the symposium of Genetics hold in Japan on 1956.
Sincerely yours Tetsu Nakayama
P. S. I asked to Mr. Iino to hand a gift to you. I should be pleased if you would accept it.
